Quick explanation, starts out with a process list, filters for apache2, removes the grep command from the list, prints the second column, uses pmap to display memory usage, then grep to filter out the mapped memory. Again printing the fourth column, then using cut to remove the K, and awk to sum up the records. NR in awk is the number of input records seen so far.

To get MaxClients divide your total memory (minus some margin for other system processes) by the average process memory usage to get the number for MaxClients.

Create usb net inst device for x41 tablet. Because of conflicts with SATA and the usb cdrom I couldn’t get an install to work with the usb cdrom. I could get the installer to start, but it wouldn’t detect the hard drive no matter what I did. I tried loading t he drivers manually, but nothing worked. I decided to try my luck with an old Lexar Jump Drive (256M). It worked! See my notes below.
